Maryland is subject to flooding from several different sources. Flash floods tend to come after short periods of heavy rain and most often affect small streams and creeks. General flooding comes from more prolonged steady rain and tends to affect larger streams and rivers. Major rivers such as the Potomac and Susquehanna often reach flood stages because of events in distant areas of their watershed. Finally, hurricanes and tropical storms can cause surges that create tidal flooding along Maryland’s bays and their tributaries.
Flooding is a very common weather event that has caused some of Maryland's worst disasters. From 1995-1996, Maryland had a number of major floods that resulted in two disaster declarations. The rules are simple where flooding is concerned: make sure you're insured and head to higher ground.
There is no such thing as a "flood proof" area. ANY area can flood, even high ground. If you are faced with a flooding situation, here's what to do:
Do not drive through flooded roadways. The road may not be there. Follow the instructions given by emergency officials. If told to evacuate, do so!
